Thanks, will surely take it in consideration for future usage.

It's not clear if it is possible to assign a procedure to a user-defined trap number. I tried to do something like: PROCEDURE MyTrapper; BEGIN Out.String("MY TRAPPER"); Out.Ln END MyTrapper; ... Traps.ShowRegs(FALSE); (* simplified trap log *) Traps.Assign(100, MyTrapper); ASSERT(FALSE, 100); ... bu...

Thanks a lot, great help from you as usual.

I have take a quick look at the HCFiler for Cortex M3. It looks very appealing in bare-metal applications needing to store data on persistent storage (e.g. from long duration tests). Should I expect big difficulties in adapting such code to run on Nucleo F767ZI (Cortex M7) ? Is there already a plan ...

There's a strange behavior in my environment (Cortex M7). Let try the following test. It takes 5 seconds whatever the CPU clock. I also performed a HW reset before each run with different clock. Maybe I'm missing something... MODULE SpeedTest; IMPORT Main, LinkOptions, Out, Clock; VAR i, x, secs: IN...

The Cortex M7 used in the STM32 MCU has a six-stage dual-issue pipeline.
So I guess that that loop is executed faster than expected for such reason.

Thanks for all the info on timing.

How much precise is the Timers.Delay() in terms of the generated wait interval when using a timer initialized with Timers.uSec as unit? Also, is there a way (by other means) to generate a specific delay below 1 us ? I can guess something like a FOR loop with EMIT passing a NOP instruction... (clearl...

Thanks, using PUT and GET in leaf procedures for critical code can be fine.

I suppose GPIO.Put() and GPIO.Get() are not valid inside a leaf procedure, do you confirm?
If so, it would be helpful to allow that. I have a user case in fast bitbanging where
a protocol could be implemented by calling leaf procedures just operating on GPIOs.

Nice!
Which Nucleo board did you use?
Is the AdaFruit 1.8" TFT Display shield directly pluggable into that Nucleo board
or is there any additional HW trick to get a full system working?
Is the backlight control implemented? If so, how good is the quality?
